The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
<h3>What is the speed of wave?</h3>Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,
Here, (f) is the frequency and (λ) is the wavelength.
The frequency is inverse of time. Thus, the value of frequency in time t is,
The speed of the wave is 0.5 m/s. Put the values in the formula,
Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Answer:
The Height is H = 70.02 m
Explanation:
We are given that the
Initial length is = =
from what we are told in the question the circumference of the circle is =
This means that the Radius would be :
Let C denote the circumference
So
=>
We are told that 1-meter bar of steel that increases its temperature by 1 degree C will expand meters
Hence
The final length would be
Where T is the change in temperature is the Coefficient of linear expansion for steel
let denote the final length
So
Now the Height is mathematically represented as
